Abstract

The invention discloses a hot dip galvanized sling enabling surfaces of workpieces to be resistant to zinc ash, comprising a pedestal, a first lifting device, first lifting rods, hooks and membrane breaking blocks, wherein a plurality of first lifting rods are arranged under the pedestal, the tops of the first lifting rods are connected to the first lifting device, the first lifting device is fixed to the bottom of the pedestal, the bottoms of the first lifting rods are provided with the hooks for hanging workpieces, the first lifting rods are provided with the membrane breaking blocks, the upper surfaces of the membrane breaking blocks have conical surfaces, and the lower projections of the membrane breaking blocks shade the lower projection of the workpieces. The invention arranges the membrane breaking blocks on the first lifting rods so that the membrane breaking blocks can break the zinc ash film on the surface of a zinc pot when the sling lifts the workpieces, so that the surfaces of the workpieces are not easy to stick to the zinc ash.

Description

【Technical field】 [0001] The invention relates to the technical field of hot-dip galvanizing, in particular to the technical field of hot-dip galvanizing hangers. 【Background technique】 [0002] Hot-dip galvanizing is to make the molten metal react with the iron substrate to produce an alloy layer, so that the substrate and the coating are combined. Hot-dip galvanizing is to pickle the steel parts first. In order to remove the iron oxide on the surface of the steel parts, after pickling, it is cleaned by ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride. , and then sent to the hot-dip coating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Spreaders are used during hot dip galvanizing. The existing spreader is easy to adhere to the zinc dust on the surface of the zinc pot on the workpiece when the workpiece is lifted out, which will affect the quali...
